Canopy of working vehicle

a working vehicle and canopy technology, applied in the direction of roofs, pedestrian/occupant safety arrangements, vehicular safety arrangments, etc., can solve the problem of low workability of the operator's seat when the operator is reverse-rotating, and achieve the effect of reducing the number of components forming the frame of the canopy, facilitating assembly, and reducing manufacturing costs

Benefits of technology

This design facilitates easier and more comfortable seat rotation, increases the strength and rigidity of the canopy, reduces assembly complexity and manufacturing costs, and enhances the aesthetic appeal by minimizing components and ensuring a smooth, unobstructed view.

Problems solved by technology

However, in the tractor disclosed in patent document 1, the space between the operator's seat and the safety frame is narrow, and thus is troublesome when the operator reverses the operator's seat and again sits on the operator's seat.
The workability when reverse rotating the operator's seat is thus low.

Embodiment Construction

[0036]An example of the present invention will now be described using the figures. FIG. 1 is a side view of the entire backhoe loader including a canopy. The work vehicle 1 is a backhoe loader, where the loader 2 serving as a loading device and a drilling device 3 are attached to the work vehicle 1. A bracket 4 is arranged on both left and right sides of the bonnet of the work vehicle 1, which bracket 4 is fixed to the vehicle body frame of the work vehicle 1. A canopy 5 is arranged on the vehicle body frame, and the operator operates the work vehicle in the canopy 5.

[0037]The structure of the frame configuring the canopy will now be described using FIGS. 2 to 4. FIG. 2 is a plan view showing the frame structure of the canopy, FIG. 3 is a side view of the same, FIG. 4 is a perspective view of the same, and FIG. 5 is a plan view showing the structure of the top frame. The canopy 5 is configured by front frames 7, rear frames 8, a top frame 16, and a front top frame 17. The front fram...

Abstract

A canopy of a working vehicle has, therein, a forwardly and reversely rotatable seat and enables an increase in the rigidity of a canopy frame with a low cost and simple structure. Frames forming the back part of the canopy are disposed radially from the rotating axis of the seat in the canopy in plan view and bent toward the inside of the canopy. The heights of the bent points of the frames are generally aligned with the height of the seat surface of the seat and disposed in the canopy.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a structure of a canopy arranged in a working vehicle, more specifically, to a frame structure of the canopy having, therein, a rotatable seat.[0003]2. Background Art[0004]A work vehicle called a Backhoe Loader is conventionally known in which a front loader is attached to the front part of the tractor vehicle body, and a backhoe is attached to the back part (see e.g., patent document 1). In the backhoe loader, the operator's seat is disposed in a freely forward and backward reverse rotatable manner on the tractor vehicle body by way of a reverse rotation support device, where the operator's seat faces the front when the tractor is traveling or when using the front loader and the operator's seat faces the back when using the backhoe by the reverse rotation support device. The reverse rotation device of the operator's seat is configured by parallel links and a turntable. A ROPS (Roll Over...
